8 Claims.

This invention relates to a bagging machine for the purpose of holding a bag in open condition while it is being lled; the machine being of a construction to take advantage of the weight of the bag contents to close the bag and hold the same in closed condition while the bag mouth is being secured as by sewing or otherwise.

Objects of the invention include the provision of a bagging machine which is constructed and arranged to automatically close the bag and hold the bag mouth closed when desired by the operator, and in which the weight of the bag contents acts to close the bag and is taken advantage of for maintaining the bag mouth closed for securing the same.

Further objects of the invention include the provision of a bagging machine comprising a support, pivoted arms on the support, and means to hold the arms in condition for supporting a bag in open condition, the arms being of a nature to move toward each other, upon release of the holding means, under the influence of the weight of the bag contents, so that the mouth of the bag is closed and the lips of the mouth are held adjacent each other for ease in securing the lips together as by sewing or otherwise.

A still further object of the invention resides in the provision of a bagging machine comprising an elongated frame, an upright guide on said frame, a pair of swingable arms pivoted at opposite sides of the frame and having means located in said guideway for guiding the same, said arms being positionable in spread apart open psition, rollers on the arms provided with bag holding pins extending therefrom for securing the lips of the bag mouth in spread apart open condition, the weight of contents of the bag tending to bring said arms and rollers toward each other; there being latch means provided to prevent such action until the bag is iilled and the operator desires to permit the arms and rollers to come together to close the mouth of the bag, and including means to hold said rollers in a position to support the bag in both opened and closed conditions thereof, said rollers being releasable when the bag mouth has been secured so that the bag itself will rotate the rolls to a position wherein the bag is dropped from the pins and is free from the rollers.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 is a top plan view of a machine embodying my invention and showing the same in open bag holding position;

Fig. 2 is a view in end elevation of the machine of Fig. 1 looking in the direction of the arrows 2;

Fig. 3 is a view similar to Fig. 2 but showing the bag lled and closed;

Fig. 4 is an enlarged cross section through the rolls showing the bag closed; and

Fig. 5 is an enlarged detail View showing a roller latch.

According to the embodiment of the invention chosen for illustration there is provided a generally rectangular elongated framework which is adapted to be set on the floor or other support, this framework comprising iixed corner members IU which may be secured at their ends and sides by frame members I2, I4. Frame members I2 at the ends of the frame are spaced above the oor and support one end of a guide member I6 which is longitudinally slotted as at I8 for a purpose to be described. Guide member I6 may also be supported intermittent the ends thereof by braces 20, it being noted that the guide member I6 is rigidly supported in xed relation to the frame I0. Guide member I6 extends vertically upwardly above the upper ends of the frame I0 as will be apparent from Fig. 3.

At each end of the frame I provide arms 22- and 24 which are rigidly connected together as at 26, the arms 24 being pivoted at 28 to the frame. A handle 30 pivotally joins arms 22 and projects outwardly through the slot I8 in guideway I6. Braces 32 are utilized to more rigidly secure the parts and some latch means such as removable pins 34 may be utilized to maintain arms 22 in the horizontal position shown in Fig. 2`

with the arms 24 vertically disposed.

At the junction of arms 22 and 24 I provide longitudinal rollers 36 which are adapted to rotate on axial pins 38. Rollers 36 are each provided with a series of extending pins 4U, these pins being preferably rigidly secured to the rolls for the purpose of penetrating the material of the bag to be filled so as to support the same in position.

As more clearly shown in Fig. 5 each roller is provided with a notch as at 42, these notches.

being adapted to receive the end of a lever for the purpose of maintaining the rolls in fixed position relative to arms 22 and 24. In Fig. 5 it will be noted that any force on pins 40 directed to the left or counterclockwise will not be able to move the roller 36 from the position wherein the pins..

extend upwardly vertically. However, upon moving lever 44 in a counterclockwise direction, the roller shown in Fig. 5 will be free to rotate.

I also may provide guards 46 pivoted on the rolls or adjacent thereto for the purpose of covering the pins as shown in Fig. 1 while the bag is being filled, these guards being swung out of the way when the bag is being loaded on the pins. A

canvas or other fabric strip 52 may be secured to the rollers 36 for the purpose of supporting the bag as it is being filled.

In the operation of the device, a bag such as at 48 is secured over the pins 40 with the apparatus contents 0f the bag will tend to draw the armsl and rollers down toward each other but this action is prevented by the latch 34. When the bag is filled, the latch 34 is actuated to yrelease the swinging arms which clearly will swing down toward each other from theFig.. 2 position tothe position shown in Fig. 3 and thus the lips 5!) ,are brought together. The lled bag is maintained in this position by the pins 4d which are still prevented vfrom rotating relative to the arms 22, 24 by latch 34, and this provides a very convenient method-of closing the lips vi) together as byvsewing or by clips or by any other means desired.

CG'nceffthe bag has Ybeen secured at the mouth, thell'a'tches 44, which are now adjacent each other as shown in Fig. 3, are actuated so 'as to release the-rellers-whichthen ret-ate `toward each other, the .pi-ns passing therebetween and the bag dropping therefrom ior -easy removal from the machine. In 4order to reload the bag the handles 30 are actuated to brin-g the arms 22, 24 and rollers 36 back to original open or spread position, and latch 34 Y is utilized to hold the arms in this position.

This invention will be seen to provide a simple bagging -machine which is -very easily operated and'which depends very slightly upon the operator. The closing of the bag is completely automatic and the machine will always close the mouth of the bag in exactly the same Way, it being very important to note that advantage `is takenv of thev weight of the bag contents to insure this action. Also, the bag is nlled horizontally, both ends being closed, and the sewing provides va longitudinal seam, as distinct from the conventionalmethod of filling bags from the ends.

Having thus described my invention and the advantages thereof, I do not wish to be limited tothe details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

`1. In a device of the class described, a support, separate means on said support selectively mov-able to and from each other, said means being effective to support the lips of a bag in open condition 'when said means are separated, means to hold said bag holding means lin spa-ced relation, saidv bagholding means being con-V 3. In a device of the class described comprising a support, pivoted arms on said support, bag holding means on each of said arms, said arms adapted` to be separated, the weight of the contents -of y-aloafg held-by sa-id'means tending .to bring said bag holding means together, and means selectively operable to hold said bag holding means in spaced relation.

4. In a device of the class described, a support, a `pair Aof pivoted arms on said support, said arms being adapted to be swung to and from each other, bag holding means on said arms for supporting a bag therebetween so that the weight of the contents of the bag tends to bring the arms toward each other together with the bag holding means, andv meansv selectively operable to hold said arms separated.

5.5,A bagging machine comprising a support, pairsof `connected arms pivoted on the support at spaced points .for swinging movement 'to and from each other Iin vertical planes, means 'to .releasably hold the arms apart, a roller on each pair of arms, pins on the rollers, releasable means to the rollers non-rotatively relative to the arms, means on. each roller to hold a bag, and a. strap secured to the .rollers and supporting theY bag.
